North Star uses a much larger, wider, stronger caster than any other manufacturer. Full 6 inch diameter American-made industrial ball bearing casters are rated at 300 pounds each (or 1,200 pounds) and roll easily, even over rough or contaminated floors. All four casters swivel for easy maneuvering and two have foot-operated parking brakes.

Shelves are supported at each end by brackets of a unique design that simply drop into square holes spaced every 2 inches along the corner uprights. The spacing between shelves and the number of shelves is instantly adjustable without tools. All shelves except the bottom one, which rides directly on the base, can be placed at any level so there is never wasted space and conveniently slide in and out. For low pieces, such as tiles, the truck can hold as many as 22 shelves.

This is the only such truck in the world engineered from ground up to ship by UPS for lowest freight cost and quickest shipping.

The truck is made entirely of heavy 14-gauge steel with North Star's blue powder coat finish. Each truck comes with four pair of shelf brackets, which will yield five shelf levels (the base carries the fifth shelf). North Star shelves are simply 24" x 36" rectangles of 1/2" finished plywood. Those who need heavier shelves, some other configuration (such as two 12" x 36" shelves per level) or who want to save on shipping cost find it easy to make their own.
